Varric... abomination... This man was a spirit of Thedas? A demon? Fenris is immediately on guard, backing up towards his door where he knows his great-sword will be placed up against the doorframe just inside it.

"Then you are a demon of Thedas? You are from the Fade."

Looks like he came across the wrong person to help because Fenris is pretty much not very friendly with such things as abominations.
